Description

1351933 (1) Description of the Invention [Technical Field of the Invention] The present invention relates to a wristband having a chain loop formed thereon and which is made of a rigid material. [Prior Art]

The strap is a link made of a rigid material that is screwed to the flexible core, the core being flexible. For example, a conventional strap with one or two chain snap ring parts, the strap end. A link made of a rigid material is more durable and stronger with a strap. Therefore, the skin (ie, not allergic) and highly resistant, including the tape assembled in the joint portion, has been disclosed in the prior art, a plurality of patents EP 0 030 705, which can be substantially parallel to the hexahedral rigid member. Each of the steel elements has two convex portions on opposite sides, each of which has a plurality of parallel links formed by a rigid chain of a bracket shape, such that the elements are allowed to be connected one after another. The strap can bend the entire watch band required, or has a chain and one of the straps on the strap to make a rigid decorative part, but also the rigid material used must be selected from the types suitable for wear. . In the table of the rigid link on the central core. Explain the European version of the articulated strap as an example of this. A strip (chain) strip formed of a plurality of, two laterally convex portions of the surface. Each element is clamped to a straight L-shaped profile in a different orientation to form a chain. The cover is covered to maintain the rigid elements in a combined state. The strap is connected at the convex portion of the rigid member. (2) (2) of the articulated strap of the European Patent No. EP 0 030 705

The disadvantage of 1351933 is that it is formed by rigid internal components. Specially designed components 'to allow the strap to be attached. The shoe is often thick because the inner element has a convex portion so that the element of the chain must be attached and the strap can be attached. Patent No. CH 365 242 discloses that the watch band is formed by a plurality of rigid rings of a series of hooked plates of the series having opposite circular edges. The other is hooked together. These loops connect the rounded edges of the panel hooks. With regard to the foregoing documents, one of the disadvantages disclosed in the CH 365 strap is the joined strap of the rigid inner panel. The construction of the connecting element is disclosed in the patent application No. DE 1 08 1 260. The tubular member forms a link and is provided on a combined core. The cover hook is removed. By releasing some of the hook elements, the length of the strap can be adjusted, which is a steel element and can be maintained in one state. Each hook must complete the space of the inner width of the link with a part or pin. Even if the strap has one more part than the strap of the aforementioned document to complete each of the holdings assembled inside the link. This constitutes a major disadvantage because the length of the strap is not easily adjusted because of the number of links. When it is ensured that the strap of the unconnected component is properly flexed, it is necessary to have a convex portion, the thickness of the strap is not relatively thick to form a strap of the connecting member, the rigid plate, and the engagement are caught by the rigid plates, While allowing the strap to be in the thickness of the 224 patent, the thickness must be thick, to the shape of the strap, which is formed by the tubular link after the link element of the hook element. However, it is sufficient for each of the small hooks to cover the thickness of the hooks, and a rigid hook element is required to make the parts necessary and hooked, in order to reduce the table-5-(3) 1351933 The thickness of the belt, the FR 2 62 5 8 79 patent disclosure - a flexible core

The strap of the department. The flexible core is in the form of a belt, and a ring made of a rigid material is provided on the belt. One disadvantage of this strap with a flexible core, however, is that it is difficult to match the dimensions of the strap to the wearer's wrist. In order to be able to reduce to the desired size, it is necessary to go to a specialty store because one or several rings must be removed and the flexible core must be cut and connected to the other end piece. One disadvantage of this strap having a flexible core is that once the flexible core is cut to fit the wrist of the wearer, it is not possible to lengthen the strap for another person to wear the strap. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to overcome the disadvantages of the prior art described above by providing a thin strap. The strap includes a plurality of links made of a rigid material and on the flexible core and the length of the strap can be easily adjusted. Accordingly, the present invention is directed to a aforementioned watch band characterized in that a part of the length of the flexible core portion is formed by a combination of a plurality of flexible members, so that the flexible members can be removed one by one. Each of the flexible elements in the longitudinal direction of the flexible core includes a first combination portion on opposite sides and a second combination portion coupled to the first combination portion to The first combination portion and the second combination portion are assembled together to combine the elements one after another. And characterized in that the links are positioned on the flexible core to hold the respective flexible elements in their combined positions by covering the assembled portions.

An advantage of the watchband of the present invention is that the size of the strap can be easily adjusted by removing or adding at least one flexible element and one or more links from the flexible core. In order to reduce the size of the strap, first remove the end piece that engages the last flexible element from one end of the strap; then the last chain by sliding at least the last link through the flexible core The ring is removed from the free end of the flexible core. The last element can be detached from the component to which it is attached by removing the last link covering the combination of the two adjacent flexible elements. These operations can be performed sequentially or simultaneously to remove a number of links and flexible elements' until the length of the strap fits the user's wrist. Advantageously, each of the flexible elements includes a first combination portion ' on one side and a second combination portion on the opposite side and shaped to fit the first combination portion. In this way, the components can be combined one after another by assembling the mating combination parts together. After the flexible elements of the flexible core are combined, the flexible core forms a flexible strip with a uniform thickness for most of the length + ° of course. Only a part of the flexible core can be made of the same size of the flexible element. Form 'because the length of the strap does not occur over the entire length of the strap. Advantageously, the first combination of each of the composite elements can be a τ-type or a dovetail' and the second combination has a Τ-type or dovetail-shaped opening that fits over the first combination. Advantageously, the flexible core can be made from a shape having a superelastic quality. The shape memory material may be a metal alloy formed of titanium or nickel or a composite plastic material. The thickness of the flexible core may be less than 1 mm, such as about (5) 1351933 0.4 mm, but preferably equal to 0.2 mm. The core made of this material can withstand considerable traction and torsion without breaking to provide proper flexibility of the strap. Since this superelastic shape of the flexible core is a material of a billion, the normal shape of the core can be equivalent to the shape of the wrist by heat treatment. Furthermore, the elasticity of the superelastic material can be greater than four times the elasticity of the steel spring.

Advantageously, the link of the rigid material can be made of a ceramic material, cermet, or hard metal having a thickness of less than 3 mm, and is preferably approximately 2 mm. In this way, a thinner strap can be made and the strap can be given a higher ability to prevent breakage and safety. Furthermore, the material selection of the link is not overly sensitive and compatible with life. Since the parts made of the watch band are easy to manufacture and the size of the watch band can be easily adjusted, the cost can be reduced. In the following non-limiting embodiments of the invention, along with the description of the drawings, the purpose, advantages, and features of the strap having a rigid link on the flexible core will be more apparent. [Embodiment] Figs. a and b show a part of the branch of the watch band 1 in an assembled position in a simplified manner, the watch band 1 comprising a flexible core 3 and an end piece 5. A link 2 made of a plurality of rigid materials is screwed onto the flexible core 3, and the end piece 5 is fixed to one end of the flexible core. As shown, the end piece 5 can be a portion of the hook or a connection to the case (not shown). The other end (not shown) of the flexible core can be fixed to the case in a conventional manner or to the other end piece as a complementary part of the end piece 5. -8 - (6) (6)

The 1351933 flexible core 3 is formed by a first flexible portion 4'' and a plurality of flexible members. The flexible elements 4 are joined together along the first flexible portion to form a flexible strap. Each of the flexible elements 4 has an equal or size and also has a link 2 which covers the respective flexible elements 4. Each of the flexible elements 4 includes a first side having a combination portion 6 and a side having a second combination portion 7 in the length direction of the watch band. The second combination portion and the first combination portion are complementary . In this way, the corresponding combinations of the respective flexible elements 4 are assembled together one by one in a removable manner. The combination can be designed to maintain temporary contact by friction when the complementary portions are assembled. Therefore, the 'first flexible portion must also have a combined portion 4 at one end combined with the combined portion to form a belt. In this way, the respective flexible member 'belts have the advantage of being uniform over most of the length of the flexible core 3. The thickness of the flexible core can be less than 1 millimeter (mm), which is close to 0.2 mm. The first combination portion 7 of each of the flexible members 4 may be of a T-shape, and the combination portion 6 is a T-shaped opening which is complementary to the first combination portion 7. Thus the combination 7 of the flexing elements 4 can be fitted within the second set 6 of adjacent flexible elements. By repeating these operations for a plurality of other components, a flexible tape that shapes the core can be obtained. Of course, the combination can be made in other shapes, particularly one that includes at least one head and a portion that connects the head to each of the flexible elements. Of course, the width of the head is larger than the width of the arm, and the different work can be set in the form of a vertical 4 - the second can be combined with the second, and the combined thickness can be combined with the second, and the combined portion can be combined to form the center to the ground - 9-(9) 1351933 The end piece 5» of a combination portion 7 is then fitted in the first combination portion 7 of the last element of the flexible core portion 3 at step a1. In step a2, after the new flexible element 4 is assembled, the new link 2 is screwed onto the core until it contacts a last link before the band 1.

At step a3, once the new link 2 has been positioned on the flexible core, the first combination 7 of the new component remains exposed for screwing the end member thereto. In step a4, when the end piece 5 is placed at the end of the fireable core portion on the first combination portion of the new component 4, the fixing screw 10 is screwed into the threaded hole 9 immediately. The threaded hole 9 passes through the two openings 8 . Therefore, the size of the strap has been adjusted by an additional component and link. In step bl, in order to reduce the size of the strap, the fixing screw is first loosened and removed from the blind hole 9. Then at step b2, the end piece 5 is removed from the flexible core. Then at step b3, the last link 2 must be slid to remove it from the burnable core. Finally at step b4, the last flexible element 4 is removed by releasing the second combination of the last flexible element 4 from the first combination 7 of the adjacent elements. Once the one element and one link are removed from the watchband, the end piece 5 is then secured to the first combination of the last elements of the flexible core. As can be seen from the above steps, it is easy to adjust the size of the strap to fit the wrist of anyone carrying the strap without having to go to a store for this purpose. To illustrate the flexibility of a watchband formed by a plurality of links made of a flexible core and a rigid material, reference is made to Figures 3a to 3c, which are shown in a linear position, a slightly curved position, and a very curved position ( It can be the strap of the part of the strap with a maximum of -12 - 1351933 do) bending position). As before, the same strap elements described below are denoted by the same symbols and will not be described in detail. The shape of the link shown in Figures 3a to 3c is slightly different from that shown in Figures la and lb, particularly the upper portion thereof. It should be noted that each link has a first rounded portion 22 on the upper portion of the first face and a second recessed portion 23 on the second opposite face. Therefore, by juxtaposing the links 2 on the flexible core portion 3, the first convex portion 22 of one link enters the inner side of the second concave portion of the adjacent link.

By bending the watch band 1 as shown in Figs. 3b and 3c, the curved state of the flexible member 4 of the flexible core can be seen, which can move upright into the longitudinal opening 12. Because of the flexible core 3, and without the use of an articulating pin, the strap can be easily bent, particularly for example the maximum position shown in Figure 3c.

Figures 4a and 4b relate to a second embodiment of the strap which illustrates how to adjust the dimensions of the strap 1. It should be noted that the same elements of the band described below except for the combination portion and the foregoing are all given the same reference numerals as those of the elements of Figs. 1a, 1b. Therefore, the components that have been described are not described all in detail. In order to simplify the description regarding the adjustment of the strap size, the first embodiment as in Figs. 2a, 2b only mentions the addition or removal of a flexible element 4 and a corresponding link 2. Of course, multiple components and links can be added or removed in the same manner by comparison. Viewed from above, the first combination portion 27 is trapezoidal or dovetail shaped, and the second combination portion 26 is a trapezoidal or dovetail opening complementary to the first combined portion. The opening 28 is formed in the central portion of some of the components to adjust the reaction force of the watchband in a curved state. But it is also conceivable to reduce each of the flexible elements appropriately -13- (11) (11)

The thickness of 1351933, this reduced thickness may be disadvantageous because it can usually be greatly reduced. In this second embodiment, it should be noted that the end piece 5 is formed by the second portion 5b. The second portion 5b uses two ί first portions 5a which are screwed into the corresponding threads 18 of the first portion 5a by the screws 20 of the second portion 5b. Once the second portion 5b is fixed to the first portion 5a, the first combination portion 27 of the end piece flexible member has a complementary shaped recess and is required to open to the first flexible portion of each of the elements and the flexible core, because A flexible portion 27 accommodates a concave sound of the end piece. To increase the size of the watch band, the end piece 5 is first removed from the last flexible combination portion 27. Then, in step a 1, the second combined portion 26 of the evening is fitted into the final portion 27 of the flexible core 3. In step a2, after the new one is combined, the new link 2 is screwed onto the core until it is connected to the previous last link. At step a3, once the new link 2 has been positioned in the first combination portion 27 of the add-on element remains exposed to the inside of the recess 25 of the first portion 5a of the member 5. At step a4, the portion 5a is placed on the first combination portion of the new component 4, and the second portion 5b is immediately pressed against the first portion 5a. Finally, the fixing screw 20 is screwed into the threaded hole 18. Therefore, the additional components and links of the strap are adjusted. In step bl, in order to reduce the size of the strap, the first "flexible core portion is fixed to the hole 19' by the first portion 5a and the tired wire 20 and each 5 includes a sum portion 25. Therefore, it is not provided in 4' Fixed by β 25. The first t-plus-flex element 4 of the element 4: the first set of flexible elements 4 of the element touches the flexible core 3 of the watch band 1, which can be accommodated in the end piece 5 The end of a flexible core is removed in step a5 by a first set screw 14-(12) 1351933 2 0 and removed from the threaded blind hole. Then in step b2, the end piece 5 is removed. Second portion 5b. Thereafter at step b3, the first portion 5a of the end piece is removed from the first combination of the last element 4. At step b4, the last link 2 is slid over the flexible core and removed Finally, at step b5, the last flexible element 4 is removed by releasing the second combination portion 26 of the last flexible element 4 from the first combination portion 27 of the adjacent element. Once the element is removed from the watch band and After a link, the end piece 5 is then fixed to the first group of the last component of the flexible core

Joint department. It should be noted that the end piece 5 can be hinged to the second portion 5b by a hinge (not shown), and the second portion 5b can be fixed to the first portion 5a by other mechanisms. This end piece can also be formed by a clamping mechanism. From the above description, those skilled in the art can design a variety of variations of the watchband without departing from the scope defined by the scope of the present invention. Each link may be a dome having a C-shaped curved end such that the link can slide over the flexible core' and keep the jaws together. The sides of the flexible element may be provided with perforations to increase the lateral flexibility of the bracelet. As previously mentioned, the end piece can be designed to be secured to the second portion of the element or the first portion of the flexible core rather than being fixed to the first combination. Finally, a blocking member may be provided in the opening of each link and on the side of each of the flexible members to abut each link against the blocking member of the combined component to be hidden.
